It was an up weekend at the box office for Disney as its Pixar-produced Up opened with $68.11 million, beating last year's debut of WALL-E -- and less than $2 million behind Pixar's two biggest hits, The Incredibles and Finding Nemo . But it was a down weekend for the box office as a whole, with total ticket sales slightly below what they were for the same weekend a year ago, when the premiere of Sex And The City and the second week of Indiana Jones and the Kingdom of the Crystal Skull together took in $101.60 million all by themselves. The top twelve films this weekend earned $161.01 million, while last year's grossed $163.99 million. Another downer The critically well-received horror flick Drag Me to Hell -- horror flicks are rarely well-received -- took in a modest $15.83 million to place fourth in the final results. (By contrast, last December's critically slammed Saw V opened with $30.1 million.) Monday's estimates had put it in third place. But despite the down weekend, year-to-date revenue stands at $3.61 billion, up 13.63 percent over last year. Attendance is up 11 percent.
